Mill Creek Campground Accessibility and Aquatic Habitat Improvement

Mill Creek Campground Accessibility and Aquatic Habitat Improvement

Complete ADA improvements and habitat restoration work in the south loop of the Mill Creek Campground within Del Norte Coast Redwoods State Park to provide ADA compliant access from an existing restroom to nearby campsites and to improve aquatic habitat and fish passage in Mill Creek. Work will: • Use a small excavator to remove approximately 60 feet of existing asphalt trail, a culvert crossing that contains a non-ADA compliant steel plate covering and approximately 480 cubic feet (18 cubic yards) of rock debris from the stream channel; • Approximately 10-ft downstream of the existing crossing, excavate approximately two (2) 1-ft by ½-ft by 6-ft areas to create level pads for two (2) mud sills; • Excavate two (2) 12-in. wide by 2-in. deep by 20 ft long areas to create stable and level footings for two (2) double sided, single tier, rock causeways to create compliant linear grade approaches at each end of the new footbridge; • Use 12-in. x 12-in. by 6-ft long plastic lumber mudsills, Strongwell fiberglass reinforced plastic (FRP) stringers, 4-in. x 6-in. redwood post, handrails, and diagonals, and hand split redwood decking to construct a new 25-ft long footbridge; • Attach an existing buried waterline that services the restroom to the underside of the new bridge structure; • Use a small excavator to remove approximately 60 feet of existing, non-ADA compliant, asphalt trail and haul away and dispose of at a local recycling center; and • Use ¾-in. crushed quarry shale aggregate, compacted with a vibrating plate, to construct a 60-ft long by 4-ft wide hardened turnpike surfaced trail that is ADA-compliant. This project will be implemented during the months from September 15th through May 1 when the Mill Creek Campground is closed to the public. The culvert crossing removal will take place between September 15th and October 15th when the intermittent tributary does not have surface flow.
